Southward movement of the climate envelope for Liolaemus nigroviridis. Habitat projections for L. nigroviridis generated under climatic layers (GCM: MPI-ESM1-2-HR) for the years 2040 (panel A) and 2080 (panel B) under RCP 8.5 conditions. In both panels, the blue outline indicates the current distribution with a probability presence > 0.6, as generated by the model (based on the Random Forest algorithm). The red vertical lines represent the climate envelope expansion towards the south in the Andean mountain range. The pink rectangle indicates the area that remains towards the future in the Coastal mountain range (near Coltauco). These maps were produced in the R environment (R Core Team, version 4.3.2) using the packages: BIOMOD2 version 4.2.4 (Thuiller et al. 2023) and TERRA version 1.7.65 (Hijmans et al. 2023). The filtering based on the presence probability threshold > 0.6, shown and represented by the blue outline, was performed using the THRESHOLD COLOR function of the ImageJ software (Schneider et al. 2012), applied to the BIOMOD2 current projection. The spatial integration of the layers, the blue outline, measurements, and integration of red vertical lines was performed using QGIS software version 3.32. Coordinate system: WGS84.
